Windows 10 on Mac Problem

I am trying to install Windows 10 via Boot camp on my MacBook Pro 10.13.6 for about 8 hours. I have tried all of the quick fixes I've found online that I'm capable of like Time Machine and clearing storage but nothing has worked. I am not very well versed in this world and literally all I want to do is download Age of Empires lol. I am also not sure why it won't work as its a brand new Mac :(

I am in 14 day hotel quarantine in Sydney Australia and I'm just looking for a way to kill time by gaming. If anyone could help me that would be amazing. Would anyone be willing to FT or Zoom me... I'm desperate lol
